    Expectations for AMD8700G

    in PC Hardware and Related Software

    Posted

    Just received and installed everything. I kept my old windows 10 and had to reinstall some drivers and Ryzen Master (showed a 6 core cpu before reinstalling).

    After all, I am not that impressed in DCS. While having like 30% more performance in Cinebench R23, I hardly notice improvments in DCS with VR(G2).

     So is the 7800x3d just also limited with  current DCS or are there any hints what I could look for…

    I would be careful of bigger motion ranges. I just needs a longer time to get there, so sometimes the immersion can be affected by to long travelling distances. You want it fast and sharp, espcescially when flying a jet. Take a look at my carrier launch (link in signature) and compare it to their movements on their website. My first impression was, that they need more time to reach the final position... But still it looks like a promising product!

    Hi, I am not using this product, but the PS-6TM-150 product from Motionsystems.

    I have been using it for more than 3 years and am extremely satisfied.

    You should pay attention to the following things when buying:

    • Does the manufacturer offer functioning motion compensation? All movements of the platform must be compensated for in the VR headset, otherwise you will permanently change your position in the virtual cockpit.
    • Does the manufacturer offer functioning software with sufficient setting options for how the forces are transferred from the platform? In the video on their website, for example, I can see that the platform rolls to the side in turns. This is wrong, as rolling to the side simulates lateral forces that hardly ever occur in flight (otherwise every Airbus would spill coffee in turns). This can be configured if the user wishes, but the important thing is that you can change it.

    Motionsystems offers both points perfectly (among other advantages), but also has its price.

    I would like to upgrade the CPU of my current system (AMD 5800x + RTX4090). I've already realised that the AMD 7950X3D has no real advantages over the 7800X3D respectively that the price-performance ratio of the 7800 is significantly better.

    But now I read that the new AMD 8700G CPU is due to be launched at the end of the month. There are no benchmarks yet. What is your expectation / opinion compared to the 7800? Will this be another noticeable step forwards, or is it just cosmetic?

    PS: Of course, the upgrade also means a change of mainboard and RAM...

    Vulkan API with Reverb G2

    in Virtual Reality

    Posted

    Hey guys,

     

    I just had a chat with the  developer of my motion platform software. I informed him about future DLSS and Vulkan in DCS.

     

    To my surprise he replied:

    “I think that HP Reverb G2 does not support Vulcan. We tried to run OpenXR via Vulcan API on HP Reverb G2 and it said "not supported". Google says that WMR gogles does not support Vulcan“


    That was from a BeamNG test.

     

    Is it possible that the G2 will not run with Vulkan API?

    Missing data output after cold start

    Could’ve the export lua causing a data export failure due to it trying to send null data… which often happens with a cold n dark so I’d start by looking at the export lua sending data to the platform.

    A big culprit is any list indicator data.

    That´s it - thank you so much. 

     

    Deleted export.lua an reassigned / rewrote all commands, seems like the order of commands prevented the platform working with a cold start Huey. Don´t know, why the other modules worked with cold start, but anyhow, now everything is back were it belongs. Thanks again!

    Missing data output after cold start

    in Bugs and Problems

    Posted

    I am using a motion platform of Motionsystems, which works very well with DCS.

     

    I just experienced, that flying the Huey results in a non moving/working platform. After I have made some tests, I recognised that it is only when having a cold start of the Huey. At hot start, platform is working well.

     

    All other modules (AH64, F16/18, A10 etc.) are working fine with cold and hot start. So it is only the cold start of the Huey, that seems to prevent any data putput to the platform. Any chance to have a look into it?

    Turbulence

    in DCS 2.9

    That's not quite true. Turbulence is always a result of wind shear. Either vertically or horizontally. If there's no shear, there'll be no turbulence.

    Near the ground, shear is mostly a result of obstacles. Higher aloft, it's more dependant on frontal activities (that includes jetstreams), but gravity-waves may fravel downrange of ground-obstacles (eg. mountain waves) for up to a thousand miles, so it's a mixed bag. Hence if you travel at high wind-speeds, but no shearing layers, you'll be fine and won't have any turbulence at all.

    For thermals, you'll need a good representaion of atmspherical dynamics (such as convective potential vs capping layers, etc) and ground-air interaction. So far, our "beautiful clouds" (TM) are mostly stratus or cirrus type. The real fun, however, only starts with convection and multilayer CB clouds and associated atmospheric dynamics.

    At the end, you'll have to compromise between fidelity and game-code limitations. It would be cool if DCS could depict actual weather conditions, though.

     

     

     

     

    We both mean the same. However - it is all too quite from 300ft above ground on.

    Yes, the turbulence, as you feel it, becomes lower as you climb. It is well known phenomena, because the correlation length of the turbulence becomes longer with altitude.
    Tests conducted shows that strong (for pilot's opinion) turbulence at 300-500 m feels like very light at ~2000 m and higher.  It is not relevant for in-cloud thunderstorm turbulence because it has very different nature and velocity distribution.

     

    Of course are turbulences at higher altitudes lighter than close to the ground, but we are not talking about lighter turbulences but no turbulences at all. It simply isn´t realistic that in stormy conditions there are no gusts at all at higher altitudes. We all know them when travelling with even heavier Airbus and Boeings and I am not talking about flying through a thunderstorm cloud. So great your turbulences are close to the ground, so much I miss them at higher altitudes (happy to have them "lighter", but I just can´t see any of them).

    Turbulence

    It is not correct to say that turbulence in DCS works only with wind. Yes,  setting the wind speed sets a small amount of turbulence that allows to fly in relatively comfort conditions. But the turbulence itself can be set independently. In this case plane acceleration can jump very severe.  

    For example, if the dispersion of g-load is 0.3 and more,  pilots describe it as "very strong", so it's possible in DCS have the same dispersion, especially at lower altitudes, because the size of turbulence (correlation range) increases with altitude that leads to decreasing "bumps".

    If you want to encounter turbulence at higher altitudes you need to set wind speed in the layers quite different (speed and/or direction).
    These are a sample how DCS turbulence works, and what is correlation length or range. Please keep in mind, that the turbulence in DCS is not a function of time affecting a plane, it is SPATIAL function that means that the planes flying in close formation will be affected by the similar (correlated) vectors (but not identical) depending on the correlation length.
    And, by the way, it's not static - hovering helicopter will be bumping as well.

     

    Dear @Yo-Yo,

    thank you for your detailed answer.

    Since my platform provides a very good output of turbulence, I have made a few tests based on your explanations.

    I have given strong winds in very different (partly opposite) directions via the possible altitude levels. I set the turbulence value to 25.

    Result:
    Flying very low, I did not feel any turbulence over level terrain. As soon as I flew into a mountainous terrain, the turbulence increased noticeably just above the ground.
    When climbing up to 10,000 feet, I didn't notice any turbulence at all as I crossed different altitudes with different winds; above a few 100 feet, it simply stops.

     

    I then selected Summer Thunderstorms in Basic Weather, set Turbulence to the maximum value of 197, and again specified very strong winds (50-60 knots) in opposite directions.

    Result:
    Flying very low, I now noticed quite strong turbulence over level terrain, which increased again over mountainous terrain (this was then a hell of a ride on the platform).
    However, when I leave the immediate vicinity of the ground, the turbulence stops again. I do notice that when crossing the different wind directions (with the same course) my Velocity Vector indicator moves from right to left and thus the aircraft (A10) is exposed to the different winds, but this is a very smooth process without any turbulence.

    What we are looking for is gusts / turbulence even across all air layers. It should be possible to set a value for this - e.g. per air layer. The current value for turbulence is obviously only valid for the immediate vicinity of the ground.

    Turbulence

    in DCS 2.9

    Being probably a big exception to flying DCS on a motion platform, I can't stress enough the importance of turbulence.

    I also fly Cessnas myself (up to "heavier" Mooneys) and yes, there is rarely a flight that is truly calm. When there is a lot of thermals, as described above, it can be really unpleasant, even for me as a pilot. And yes, with increasing weight the planes naturally become calmer, so I don't have the expectation that an F18 will shake like crazy when there is turbulence.

    In DCS I find that @Sedlo, for example, has incorporated quite good wind and turbulence effects in his missions / campaigns. As soon as I take off from Carrier, I notice clear turbulence close to the ground on my plattform. In DCS, unfortunately, this always decreases significantly towards altitude, so that a flight above 500 feet already becomes very calm (except of wake turbulences!).

    I believe that DCS actually simulates the turbulence quite well, as it is very real for me on the platform. But the turbulence actually only exists close to the ground and should be experienced equally at all altitudes. Because it is not always the ground turbulence that causes problems, but sometimes also the turbulence at high altitudes.

    Maybe someone from ED (@BIGNEWY?) will read this and see if there is a better way to simulate turbulence at different altitudes.

    DirectX adapter for Brunner FFB Joystick ready

    Hardware trim is only (partially) useful when the normal trim does not work (normal CLS2SIM use).

    The real  F/A-18 trim does not move the stick (just like the F-16 and Mirage 2000). So, the Brunner DirectX mode is working as intended.

    … and BrunnerDX is no longer needed, although it is a very fine piece of software nevertheless.

     

    Thanks a lot - that explains it very good. So I will test Brunner DirectX with other Moduls to see if hardware trim is working there. No need to have it in the F18.

    By the way - what force settings are you using in Brunner DirectX. Constant Force? Or Sinus? Or Spring? I am very confused, since (at least in the F18) I never felt quite a difference.
